________________________ Notes ________________________
Installing a package in a nondefault location means that you must update the
corresponding modulefile; you m ight need to ed it t he PATH and MANPATH
environment variables. Other changes are based on the software package and
its dependencies.
If you have installed a variant o f the pa
ckage, you might need to create a parallel
modulefile specifically for the v a
riant. For example, you might have a stand ard
application that you need to keep se
parate from a beta version of the same
application; in this case, you wou
ld set up a parallel modulefile and adjust it
accordingly.
